- FLY SPINNER ATTACHMENT Filed May 29, 1956 INVENTOR. pidmm+ Brbankh BY United States Patent FLY SPINNER ATTACHMENT Helmut Berberich, Westheim, near Augsburg, Germany Application May 29, 1956, Serial No. 588,133 Claims. (Cl. 57-115) The invention relates to a fiyer top attachment which can be detachably fixed to the head of a fiyer and which is used to increase the twist imparted to the thread or roving between the delivery rollers and the fiyer top.

In known constructions, the fiyer top attachment is constructed in the manner of a cap. There are certain difiiculties in fixing these caps, which are of low height, so that it cannot always be guaranteed that the caps can be mounted efiiciently and satisfactorily. In addition, these flat cap-like attachments have the disadvantage that when the bobbins are dotted the thread reserve becomes looped behind or underneath these caps at the fiyer top, so that thread breaks occur upon recommencing winding.

According to the invention a fiyer top attachment is provided Which comprises a cylindrical neck which extends throughout the entire height of the fiyer top and surrounds same, and the said neck including an opening through which the thread can issue. This fiyer top attachment advantageously consists of an elastic, yieldable synthetic material, so that it can be pressed firmly on to the flyer top without any risk of breakage.

This novel fiyer top attachment, comprising a long neck mounted fast on the fiyer, can be fixed in a simple and reliable manner. The attachment makes a good fit over the entire length of the fiyer top, thus preventing the said attachment from being mounted obliquely. It is also important that when the bobbins are doflfed, the thread reserve can no longer become looped on the fiyer top and thus thread breakages are avoided when operations are resumed.

One constructional example of the fiyer top attachment according to the invention is illustrated in the drawings, wherein:

Figure 1 is a vertical sectional view of the upper part of a flyer with a fiyer top attachment;

Figure 2 is a plan view of the attachment;

Figure 3 is a plan view of a metal sleeve used for securing the attachment on the fiyer top.

In the drawings, 1 designates a fiyer and 2 the fiyer top. Fixed to the said fiyer top is an attachment 3 which imparts a twist to the thread or roving 4 and which, as will be seen from the drawings, comprises a neck 5 which surrounds the flyer top 2 and extends over the whole length of the said top, and a thread outlet opening 6 is provided in the said neck. This novel fiyer top attachment 3, 5 is preferably made of an elastic yieldable synthetic material, so that it can be pressed firmly on to the fiyer top without any risk of breakage, thus guaranteeing a secure fit.

The attachment can be secured on the fiyer top by the arrangement according to Figure 1. In this arrangement, the neck 5 is provided with holes 6, 6a correspond ing in diameter to the hole 7 formed in the fiyer top, and a thin-walled metal sleeve 9 is provided with an oval opening 8 through which the thread can travel, and the said sleeve is adapted to be inserted in the aforesaid holes as shown in Figure 1. After the said sleeve has been inserted, the two ends thereof are belled out at 10 in the manner of a hollow rivet with a suitable pincers-type tool so that the sleeve is thus prevented from leaving its location.

When an elastic synthetic material. is used, the fiyer top attachment 3, 5 can be cylindrical, but where appropriate it may also be slightly conical in shape corresponding to the conicity of the fiyer top 2.

The thread-guiding upper portion 3 of the fiyer top attachment can be of any desired shape, but preferably this twist-imparting portion has a per se known polygonal opening 11, and comprises a cylindrical rim 12 against which the inwardly travelling thread bears.

If necessary, the upper portion of the fiyer top attachment (thread-guiding elements 12 and 11) may also be made of metal. In the example of Fig. 1 this upper portion is embodied by a cap 13 of metal.

Furthermore the neck 5 rests with its front face 14 on the shoulder 15 of the fiyer, as shown in Fig. 1. In this way an accurate fit of the attachment 3 will be secured. Furthermore the roving 4 is prevented from slipping between the face 14 and the shoulder 15, so that thread breakages are avoided.

What we claim is:

l. A device for attachment to the fiyer of a fly spinner for obtaining increased thread twist including an axially bored neck member having two diametrically opposite radial openings extending from the bore and a thin walled metal sleeve having an opening in its wall corresponding to the bore in the neck member, the said neck member being adapted to fit over the entire length of the fiyer top to surround the same completely and the said metal sleeve being adapted to fit in the radial openings so as to locate the neck member on the fiyer top the arrangement being such that the thread may be led down through the axial bore fiyer top and opening in the wall of the metal sleeve and out through one of the radial openings.

2. A device as claimed in claim 1 in which both ends of the metal sleeve are belled out to fix and locate the sleeve in the radial openings.

3. A device as claimed in claim 1 wherein the neck member is made of an elastic synthetic material.

4. A device as claimed in claim 1 wherein the neck member is made of an elastic synthetic material and is of conical shape.

5. A device as claimed in claim 1 wherein the neck member is made of an elastic synthetic material and has a polygonal opening surrounded by a metal cylindrical rim.
